Definitions

  • the present invention belongs to the technical sector of assemblies and apparatuses that aim to assemble support structures, and in particular, assembling support structures for solar collector panels.
  • the document ES1057555U describe a device for forming solar collector supports comprising a series of support means on the ground or an inclined floor, a set of longitudinal support bars forming a square base arranged on the support means and a set of oblique vertical bars holding another set of support bars that determine the plane on which the solar panel rests.
  • the support means are formed by square bases, each one of which comprises a set of vertical studs on which a plate is inserted. On each plate there is a foot, which is a vertically arranged elongated part.
  • Said foot is inserted into a double-angled part that connects the ground supports to the structure and which is normally fastened by being screwed to it.
  • the double-angled part is, in turn, normally joined by means of a threaded joint to junctions, or it can be replaced by flanges adjacent to the junction, forming a single part.
  • the junctions are a set of parts that enable joining between the horizonal bars and the oblique bars. This joining is also carried out by means of screws that are inserted into holes made in the parts to be joined.
  • the present invention describes a set of joining elements for joining by means of fitting and clipping between the different bars and between the support means and the bars forming the base of the support structure of solar collector panels.
  • the support structure of solar collector panels rests on fastening elements for fastening to the floor on which the base bars of the structure are arranged.
  • the secondary bars normally two inclined secondary bars (although there can be more than two), each of which is joined to one end of the base bar.
  • the first secondary bar constitutes the support of the solar panel; the second secondary bar according to the length thereof determines the inclination of the solar collector panel.
  • At least two substructures formed by the base bars and the inclined bars are arranged in parallel. At least two support bars are arranged between every two substructures, supported on the inclined bars. The solar collector panel rests on these support bars, although it could be used to support any other device capable of being held by a support structure.
  • the first profile is a bar profile with four, generally square, facets comprising grooves in some of the faces thereof.
  • the inner part of at least one of the grooves comprises ribs for fitting some of the joining elements.
  • This first profile is normally used for the base bars of the structure and for the support bars that form the plane on which the solar collector panel rests.
  • the second profile is normally an L-shaped profile. This second profile is preferably used in the secondary bars of these installations.
  • the invention has a quick fastening device for fastening between the elements of the structure and the fastening means for fastening to the floor, and for joining the elements of the structure together.
  • the quick fastening device in its preferred configuration has an open shape and comprises two arms, the first arm is a central insertion arm that fits into inner ribs made in one of the grooves of the first profile, and the other arm is a lateral support stabilising arm of the profile.
  • the quick fastening device thus enables quick joining with the first profile by mechanical elasticity, and formal correspondence that works with the immobility thereof once inserted.
  • the quick fastening device further comprises a fastening means (for example, a hole and a screw or a 90-degree rotating lock) in the central part thereof for the joining thereof to another bar of the first profile.
  • the lateral support stabilising arm can further comprise a longitudinal slot for inserting one of the flanges of the second L-shaped profile, thus providing another way of joining a bar of the first profile and a bar of the second L-shaped profile.
  • the quick fastening device can further comprise a fin, which is arranged on the face opposite the face that has the arms, said fin comprising a hole capable of being passed through for the fastening thereof by a bolt.
  • the ends of the two arms of the quick fastening device have a shape corresponding to outer ribs made in the grooves of the first type of profile, such that they are arranged in two opposite grooves of the first profile, fastening the quick fastening device on opposite faces of the profile to the base bar of the structure.
  • the quick fastening device on opposite faces of the profile has a through hole capable of being passed through by a bolt.
  • one of the arms of this quick fastening device on opposite faces of the profile can also have a longitudinal slot for inserting one of the flanges of the second L-shaped profile.
  • each quick fastening device achieves provisional or definitive fastening, which provides enough stability to the set during the assembly thereof.
  • the fastening means of fastening to the floor is normally formed by a bolt (or other fixing element) fixed to the floor (it can be tiling, roofing, terrace, etc.) on which the entire structure is located, with damp-proofing means and height adjusting means of the bars that join to it.
  • the bolt receives the quick fastening device that is fastened by means of a nut (normally an anti-extraction nut) and that is adjusted by height.
  • the base bar corresponding to the first profile is fastened to this quick fastening device.
  • the joining of the bars forming the base of the structure and the secondary bars is carried out by fastening the quick fastening device to the secondary bars in the central part thereof to the outer face of one of the flanges of the second L-shaped profile, for example, by means of screws or other means.
  • the quick fastening device is fastened to the base bars corresponding to the first profile by fitting the arms that correspond to the shape of the first profile.
  • the joining of the secondary bars and the support bars forming the plane on which the solar collector panel rests is carried out by fitting the arms of the quick fastening device corresponding to the shape of the first profile to the support bars, and inserting one of the flanges of the secondary bar corresponding to the second L-shaped profile into the slot of the quick fastening device.
  • the support structure of solar collector panels is formed by at least two base bars (30) arranged in parallel on at least two fastening means (20), one on each end of each base bar (30). At least two secondary bars (40, 41) are arranged on each base bar (30). The first secondary bar (40) determines the inclination of the solar collector panel (60), while the second secondary bar (41) helps hold the first secondary bar (40). The two secondary bars (40, 41) are joined on the unjoined ends thereof to the base bar (30). This structure can be repeated to adapt to the required plane length. At least two support bars (50) are arranged between every two secondary bars (40). The support bars (50) form a plane parallel to the first secondary bars (40) on which the solar collector panel (60) rests.
  • the first profile (1) is a bar profile with four, generally square, facets.
  • This first profile (1) has three grooves in three of the faces thereof. These grooves have an approximate inner shape of a half hexagon and comprise a narrower part that reduces the hollow in the face of the profile.
  • the inner face of one of the grooves (100) comprises two inner ribs (101) for fitting by elasticity of a quick fastening device (10).
  • This first profile (1) is used for the base bars (30) of the structure and for the support bars (50) forming the inclined plane on which the solar collector panel rests.
  • the second profile (2) is preferably an L-shaped profile. This second profile is used in the secondary bars (40, 41).
  • FIG. 1 A side view of the structure can be seen in Figure 1 .
  • the fastening means (20) is formed by a plate (22) passed through by a bolt (23).
  • the plate (22) has a shape where it is adapted to the surface on which there is (roofing, terrace, tiling, etc.); in the figures it rests on a curved tile (21), being able to be flat on a terrace floor.
  • the plate (22) is fastened by means of a nut (24) threaded on the bolt (23) on the tile (21).
  • a quick fastening device (10) has an open shape and comprises two arms (11, 14) that emerge from a central part.
  • the first arm (11) is a central insertion arm in the square profile and it comprises two tabs (12) ending in a spear (13) that fit into the resulting lower hollow of the ribs (101) made in the corresponding groove (100) of the first profile (1).
  • the second arm (14) is a lateral support stabiliser arm of the profile.
  • the quick fastening device (10) further comprises a fin (16), which is arranged on the face opposite the face that has the arms (11, 14), said fin (16) comprising a hole (17) capable of being passed through by the bolt (23) of the fastening means (20) for fastening the structure to the floor.
  • the fin (16) of the quick fastening device (10) is arranged in the upper part of the bolt (23).
  • the height of the quick fastening device (10) is adjusted by means of an adjusting nut (25) threaded on the bolt (23).
  • the quick fastening device (10) is fastened in the bolt (23) by means of a fastening nut (26) threaded on the bolt.
  • the fit of the base bar (30) of the structure into the first quick fastening device (10) prevents vertical movement and transverse movement to the quick fastening device (10) of the base bar (30). Longitudinal movement with respect to the quick fastening device (10) is prevented by fastening means such as screws (19), for example, self-tapping screws that the first arm (11) of the quick fastening device (10) and the profile (1) are joined to, in this case the base bar (30).
  • FIGS. 4 and 5 show that the slot (15) of the second arm (14) of the quick fastening device (10) does not perform any function on the joining of the fastening means (20) to the base bar (30), which corresponds to the first profile (1).
  • two joining devices (10) can be manufactured, one in which the second arm (14) has a slot (15) for fitting the second L-shaped profile, and the other in which the second arm does not have the slot (15) for fitting the second L-shaped profile.
  • a quick fastening device in which the second arm (14) does not have the slot (15) for fitting the second L-shaped profile can be seen in Figures 4 and 5 , which represent the joining of the base bar (30) to one of the secondary bars (40, 41).
  • the quick fastening device (10) also does not have the fin (16), since this fin is only necessary for inserting the bolt (23) of the fastening means (20), and not for joining bars.
  • the fin (16) can be cut or the device can be manufactured without the fin (16).
  • the joining of the base bars (30) and the secondary bars (40, 41) is carried out by fastening the quick fastening device to the secondary bars (40, 41) in the central part thereof on the outer face of one of the flanges of the second L-shaped profile (2).
  • the joining of the secondary bar (40, 41) and the quick fastening device (10) is carried out by means of a screw (180) that passes through a hole (18) made in the central part of the quick fastening device (10).
  • the quick fastening device (10) is fastened to the base bar (30) by means of fitting that has been explained previously, and it can also have a screw to prevent lateral movement.
  • the quick fastening device (10) in the joining of the secondary bars (40, 41) to the base bar (50), is fastened to the secondary bars by means of a 90-degree closure.
  • a fin head (19) that is inserted into a groove (190) arranged in one of the flanges of the secondary bars corresponding to the second L-shaped profile, and once inserted, it is rotated 90 degrees, such that the movement of the quick fastening device (10) is prevented.
  • Figure 6 shows the first step of inserting the fin head (19) into the groove (190)
  • Figure 7 shows the second step of rotating the fin head (19) once it has been inserted into the groove (190).
  • the joining of the support bars (50) to the secondary bar (40) is carried out by fitting the tabs (12) with a spear point (13) of the first arm (11) of the quick fastening device (10) into the inner ribs (101) of one of the grooves (100) of the first profile that forms the support bars (50).
  • the second arm (14) in addition to being used as a lateral support for the support bar (50), fastens the secondary bar (40) by means of insertion into the slot (15) of one of the flanges of the second L-shaped profile (2) that forms the secondary bar (40).
  • Figures 8 and 9 show the joining of the secondary bar (40) and the support bar (50) in detail.
  • a quick fastening device is provided on opposite faces of the profile (70).
  • the quick fastening device on opposite faces of the profile (70) is a part that has an open shape corresponding to the first profile (1), which comprises a central part from which two arms (71, 73) emerge, and which has a through hole between the arms (71, 73) thereof, through which the bolt (23) of the fastening means (20) is inserted.
  • the ends of the arms (71, 73) of the quick fastening device on opposite faces of the profile (70) are fins (72) that have a shape corresponding to the outer ribs (103) of the grooves of the first profile (1).
  • the quick fastening device (70) further comprises two inner tabs (76) that are used as a seat and limit to entry and adjustment between the base bar (30) and quick fastening device on opposite faces of the profile (70).
  • the second arm (73) unlike the first arm (71), comprises a longitudinal slot (74) for inserting one of the flanges of the second L-shaped profile (2).
  • Figures 10 and 11 show an example of use of the quick fastening device on opposite faces of the profile (70), in which the joining of the fastening means (20) to the base bar (30) is shown.
